As the compartment air circulates ing the side plates to theunit. and re-circulates .through the zone of the coils The refrigeratingcoil which is indicated as a and plates or nns and neat is absorbedthereby whole at 6 comprises a plurality of parallel tubes i5 from theair, condensation occurs and causes arranged in laterally spaced pairseach of which accumulation on the coils and plates or fins of said pairscomprises an upper tube 1 and a lower moisture which should be collectedand drained tube 8. These tubes are mounted in and project away. Thefacilities forlcollecting and draining through end plates 9 and I0 andare connected 2o away the moisture must, however, be arranged in seriesby return bands II at their ends beyond 2d surfaces thereof that do notdrain into the regucirculated through the connected series of pipes 25and conveniently cleaned. the end plates 9 and III and securely xed onThe principal objects. of my invention are to the pipes 1 and 8 in amanner to insure good con- 30 provide improved moisture collecting anddrainductivity.
